php - CakePhp model name conventions -

i using cakephp,

$this->calldetail->save($data);

database table name calldetails

and class code

class calldetail extends appmodel {      var $name = "calldetail";   }

however calldetail not working, should change model name to

it seems not load model. first have load model in controller. there 2 way load model

$this->loadmodel('article');

another $uses variable

public $uses = array('article');

update

or can use $usetable specify table name

public $usetable = 'exmp'; // model uses database table 'exmp'
